Decision making python code

I am trying to make the code below make decisions between two different data sources. Basically, if the data source is m_mas it should go through one set of processes, and if it is m_rma, the coding should go through another set of processes.

I am not sure if I am using the decision making syntax correctly and would appreciate any help. Thanks.

if self.dataSource == "m_mas":
if maxSignalInDatasource < 1000:
# the little graph on the tga image has a scale
# such that 1 unit is 0.031 pixels for the range 0-1000
# Also it is displaced to the right by some pixels
offsetX = maxSignalInDatasource*0.029
offsetX += (displaceX + 23)
int(offsetX)
draw.line((offsetX, top1, offsetX, bottom), fill='#cccccc')
elif maxSignalInDatasource > 1000:
# the little graph on the tga image has a scale
# such that 1 unit is 0.003222 pixels for the range 1000-10000
# This bit of the graph is displaced another 31 pixels
offsetX = maxSignalInDatasource*0.0029
offsetX += (displaceX + 48)
int(offsetX)
draw.line((offsetX, top2, offsetX, bottom), fill='#cccccc')
elif viewMaxSignal1 < 1000:
# the little graph on the tga image has a scale
# such that 1 unit is 0.031 pixels for the range 0-1000
# Also it is displaced to the right by some pixels
offsetX = viewMaxSignal1*0.029
offsetX += (displaceX + 23)

First, what happens if maxSignalInDatasource == 1000? I changed the first if to <= 1000. Second, int(offsetX) does nothing, so that was changed to offsetX_int = int(offsetX). Third, the way you have the indents positioned in your post, everything from
elif viewMaxSignal1 < 1000:
and below will only be executed if maxSignalInDatasource == 1000. The first pair of if/elif will catch everything else. You might consider using a function also instead of the redundant code, like the following.
